I've heard loads of people say that Blackberry Messenger and applications like Twitter/Facebook aren't working on their Blackberry because they don't have a data plan (or push email).
I'm pretty sure that the BlackBerry Email Booster is the push email (correct me if I'm wrong!), but I'm not sure whether there's a data plan or not. I don't want to end up with loads of utilities that won't function!
If it helps, this is with T-Mobile UK

Because T-mobile UK are basically idiots.
They decided to split up their handling of data.
So unlike O2, orange etc, who offer a bolt-on/booster/plan that is "for blackberry and includes everything"; t-mobile UK decided, You pay £5 for Blackberry booster which is REQUIRED; but we'll hide the fact you'll need our web n' walk/internet to actually go on the internet.

Blackberry booster does 2 things: 1) makes internet work on a BB, an 2) has a 50MB fair use policy that pertains ONLY to data for recieivng EMAIL.
The unlimited internet/web n walk does 1 thing: Give you 1GB of fair use data to use on browing the web, and data for apps (FB, google maps, etc).

Without the booster internet won't work; and without internet only email will work.

Thanks so much! You've really helped - if you didn't tell me that I needed the Unlimited Internet, I would've stuck with Unlimited Texts.
Thanks again :)

No probs.
Hope it works out for you.
I had to call them up on the first day (3 different people before getting it sorted) because they hadn't activated the BB booster correctly.
Let us know if you have problems.
